Scale legend for leaflet

Question

Is it possible (or is there a plugin) which shows a legend of the current scale/zoom in one of the corners? I'm not sure if this is the correct English term so here is an image:

(google calls it id='scalecontrol' ;))

Of course it should only show up for the lower zoom levels as otherwise the distances of the northern and southern area would be too different.

After knowing the correct name I was able to find it in leaflet or here or older ones
